[0036] The power supply connector 40 is a so-called coupler and can be mounted on the power pickup connector 3 by inserting it into the interior 34s of the power pickup connector 3, as shown in Fig. Figure 14 shows that the power supply connector 40 can be removed from the power pickup connector 3 by moving it in the removal direction X2 from a state such as shown in Figure 14. Fig. 12 is shown moving. As in Fig. 4 and Fig. As shown in Figure 5, the power supply body 40 has the power supply terminals 41 and a power supply terminal retaining section 43.

[0037] The power supply connection 41 is formed in a column shape from a conductive metal, extends along the insertion / removal direction X, and is arranged along the insertion / removal direction X. The radial thickness of the power supply connection 41 is greater than that of a power supply signal connection 41a. The power supply connection 41 has, for example, a first power supply connection 41b1 and a second power supply connection 41b2. That is, the power supply body 40 of the present embodiment has two power supply connections 41. Each power supply connection 41 is electrically connected to a terminal of a power supply wire 42. The power supply wire 42 has a first power supply wire 42b1 and a second power supply wire 42b2. The first power supply connection 41b1 is electrically connected to a terminal of the first power supply wire 42b1.The second power supply connection 41b2 is electrically connected to a connection of the second power supply line 42b2.

[0038] The power supply terminals 41 and the power supply wires 42 are located in the middle of the power supply lines that supply the battery 22 with power from the charging device 49. The power supply lines are configured through the power pickup terminals 31, the power pickup wires 32, the power supply terminals 41, and the power supply wires 42.

[0039] The first power supply terminal 41b1 is formed at its pointed end with a convex engagement section 41b11. The convex engagement section 41b11 projects from the head end of the first power supply terminal 41b1 in the insertion direction X1, extends in the insertion direction X1, and can engage with the concave engagement section 31b11. The second power supply terminal 41b2 is formed at its pointed end with a convex engagement section 41b21. The convex engagement section 41b21 projects from the pointed end of the second power supply terminal 41b2 in the insertion direction X1, extends in the insertion direction X1, and can engage with the concave engagement section 31b21.

[0040] The power supply signal terminal 41a is formed from a conductive metal in a column shape, extends along the insertion / removal direction X, and is arranged along the insertion / removal direction X. The power supply signal terminal 41a has, for example, a first power supply signal terminal 41a1 and a second power supply signal terminal 41a2. That is, the power supply body 40 of the present embodiment has two power supply signal terminals 41a. Each power supply signal terminal 41a is electrically connected to a terminal of a power supply signal wire 42a. The power supply signal wire 42a has a first power supply signal wire 42a1 and a second power supply signal wire 42a2. The first power supply signal terminal 41a1 is electrically connected to a terminal of the first power supply signal wire 42a1.The second power supply signal terminal 41a2 is electrically connected to a terminal of the second power supply signal wire 42a2.

[0041] The power supply signal terminals 41a and the power supply signal wires 42a are located in the middle of the signal lines that transmit / receive signals between the charging device 49 and the battery 22. The signal lines are formed by the current input signal terminals 31a, the current input signal wires 32a, the power supply signal terminals 41a, and the power supply signal wires 42a.

[0042] In the power supply body 40, several (two) power supply connections 41 are arranged side by side in the width direction Y. Furthermore, in addition to the two power supply connections 41, several (two) power supply signal connections 41a are arranged side by side in the width direction Y on both sides of the power supply connections 41 in the width direction Y. That is, in the power supply body 40 of the present embodiment, the two power supply connections 41 are arranged side by side in the width direction Y, and the two power supply signal connections 41a are arranged side by side in the width direction Y next to the two sides of the power supply connections 41.

[0043] The power supply connection retaining section 43 is formed from an insulating synthetic resin and receives and holds the power supply connections 41. The power supply connection retaining section 43 has a pair of power supply ceiling sections 441 and 442 facing each other in the vertical direction Z, a pair of power supply side sections 443 and 444 facing each other in the lateral direction Y, and a power supply interior 44s, and is formed in a square tube shape. The power supply connection retaining section 43 has a first power supply opening 44o1, which connects the power supply interior 44s of the retaining section and an exterior, at one end of the power supply connection 41 on the side of the extraction direction X2.Furthermore, the power supply terminal retaining section 43 has a second power supply opening 44o2, which connects the power supply interior 44s of the power supply terminal retaining section 43 and an exterior at one end of the power supply terminal 41 on the insertion direction X1 side.

[0044] The power supply connection retaining section 43 of the present embodiment is located at the tip ends of a pair of first arms 56a1 and 56a2 and a pair of second arms 56b1 and 56b2 of a connection mechanism 56, which is described further below, in the lifting element 5 (see Fig. 9) attached.

[0045] The in Fig. The charging device 49 shown in Figure 1 is electrically connected to each power supply terminal 41 via each power supply wire 42. The charging device 49 is connected to an external power supply, converts the alternating current supplied by the external power supply into direct current, and supplies power to the battery 22 via the power supply wires 42, the power supply terminals 41, the current pickup terminals 31, and the current pickup lines 32, thereby charging the battery 22.

[0046] The in Fig. The lifting element 5 shown in Figure 1 moves the power supply connector 40 in the vertical direction Z of the vehicle 2 and moves the power supply connector 40 in the insertion / removal direction X, as described below. That is, in the vehicle charging system 1 of the present embodiment, the lifting element 5 is a movement section in the insertion / removal direction that moves the power supply connector 40 in the insertion / removal direction X, and is a vertical movement section that causes the power supply connector 40 to move forward and retract in relation to the opposite space 35s by moving the power supply connector 40 in the vertical direction Z of the vehicle 2.Furthermore, although not shown, the lifting element 5, according to the present embodiment, can pivot the power supply connector 40 about an orthogonal axis that is orthogonal to a plane encompassing the insertion / removal direction X and the width direction Y (in other words, an orthogonal axis extending in the vertical direction Z). Furthermore, although not shown, the lifting element 5, according to the present embodiment, can move the power supply connector 40 in the width direction Y by contacting the current-receiving connector 3. Furthermore, although not shown, the lifting element 5, according to the present embodiment, can rotate the power supply connector 40 clockwise and counterclockwise about a shaft center point extending in the insertion / removal direction X by contacting the current-receiving connector 3.

[0047] As in Fig. 6 and Fig. As shown in Figure 7, the lifting element 5 has a lifting housing 50, a pair of screw shafts 51a and 51b, a pair of first bearings 52a and 52b, a pair of sliders 53a and 53b, a pair of sliding guide sections 54a and 54b, a pair of second bearings 55a and 55b, the connecting mechanism 56, a drive source 57, a drive transmission section 58, and a pair of lifting door sections 59a and 59b. As described below, by driving and reversing the drive source 57, the lifting element 5 can move the power supply fitting 40 in the upward direction Z1 and the downward direction Z2, and move the power supply fitting 40 in the insertion direction X1 and the removal direction X2.

[0048] The hub housing 50 is recessed in the ground and accommodates the pair of screw shafts 51a and 51b, the pair of first bearings 52a and 52b, the pair of sliders 53a and 53b, the pair of sliding guide sections 54a and 54b, the pair of second bearings 55a and 55b and the connecting mechanism 56.

[0049] Each of the screw shafts 51a and 51b is columnar and extends in the removal direction X2. Furthermore, the two screw shafts 51a and 51b are arranged parallel to the insertion direction X1 and the removal direction X2. The circumferential surfaces of each screw shaft 51a and 51b are provided with a helical thread. The circumferential surfaces of each screw shaft 51a and 51b of the present embodiment are threaded from one end in the insertion direction X1 to one end in the removal direction X2, e.g., either clockwise or counterclockwise. That is, in the lifting element 5 of the present embodiment, the directions of the threads provided on the pair of screw shafts 51a and 51b are the same.

[0050] The pair of first bearings 52a and 52b are arranged opposite each other in the insertion direction X1. Between the pair of first bearings 52a and 52b, one first bearing 52a is located at the end of each of the screw shafts 51a and 51b in the insertion direction X1. The other first bearing 52b is located between the pair of first bearings at the end of each of the screw shafts 51a and 51b in the removal direction X2. The pair of first bearings 52a and 52b supports the screw shafts 51a and 51b, while allowing each of the screw shafts 51a and 51b to rotate clockwise and counterclockwise.

[0051] The pair of sliding guide sections 54a and 54b are arranged opposite each other in the removal direction X2. Each of the sliding guide sections 54a and 54b is column-shaped and extends in the removal direction X2.

[0052] The pair of second bearings 55a and 55b are arranged opposite each other in the insertion direction X1. Between the pair of second bearings 55a and 55b, one second bearing 55a is arranged at the end of one sliding guide section 54a, which is located on the insertion direction X1 side. Furthermore, one sliding guide section 54a is supported by one first bearing 52a, which is located on the insertion direction X1 side, and one second bearing 55a, which is located on the removal direction X2 side.

[0053] Between the pair of second bearings 55a and 55b, the other second bearing 55b is arranged at the end of the other sliding guide section 54b, which is located on the X2 side in the removal direction. Furthermore, the other sliding guide section 54b is supported by the other first bearing 52b, which is located on the X2 side in the removal direction, and the other second bearing 55b, which is located on the X1 side in the insertion direction.

[0054] The pair of sliders 53a and 53b is, for example, formed in an essentially rectangular parallelepiped shape. Each slider 53a and 53b has a screw hole and two through holes. More precisely, the slider 53a located on the side with the insertion direction X1 has a first slider screw hole 531 that penetrates the slider 53a in the insertion / removal direction X, as well as a first slider through hole 532 and a second slider through hole 533 that also penetrate the slider 53a in the insertion / removal direction X. The other slider 53b, which is located on the side of the removal direction X2, has a second slider screw hole 534 that penetrates the other slider 53b in the insertion / removal direction X, and a third slider through hole 535 and a fourth slider through hole 536 that penetrate the other slider 53b in the insertion / removal direction X.

[0055] Furthermore, in the pair of sliders 53a and 53b, the direction of the screw in the first slider screw hole 531 in one slider 53a is opposite to that of the screw in the second slider screw hole 534 in the other slider 53b. Moreover, with respect to the pair of screw shafts 51a and 51b, the first slider screw hole 531 is screwed to the screw of the other screw shaft 51b, and the second slider screw hole 534 is screwed to the screw of one screw shaft 51a. More precisely, the other screw shaft 51b is inserted into the first slider screw hole 531, and the screw located on the inner circumferential surface of the first slider screw hole 531 is screwed to the screw located on the outer circumferential surface of the other screw shaft 51b.Furthermore, one screw shaft 51a is inserted into the second slider screw hole 534, and the screw provided on the inner circumferential surface of the second slider screw hole 534 is screwed to the screw provided on the outer circumferential surface of one screw shaft 51a.

[0056] The drive source 57 is, for example, a motor, and the drive transmission section 58 consists of parts such as a gearbox and a chain and transmits the drive force from the drive source 57 to each of the screw shafts 51a and 51b. When the drive force from the drive source 57 is transmitted to each of the screw shafts 51a and 51b, each of the screw shafts 51a and 51b rotates about its center point. Furthermore, the drive transmission section 58 of the lifting element 5 of the present embodiment has a first drive transmission section 58a, which transmits the drive force from the drive source 57, and a second drive transmission section 58b. When the drive from the drive source 57 is transmitted, for example, via the first drive transmission section 58a to each of the screw shafts 51a and 51b, the lifting element 5 of the present embodiment rotates one screw shaft 51a clockwise (in the direction of rotation). Fig. 9 (direction indicated by arrow R2) around its own shaft center and rotates the other screw shaft 51b clockwise (in Fig. 9 (direction indicated by arrow R3) around their own shaft center. For example, if the reverse drive of the drive source 57 is transmitted via the first drive transmission section 58a to each of the propeller shafts 51a and 51b, the lifting element 5 rotates one propeller shaft 51a counterclockwise (direction indicated by arrow R4). Fig. 9) around its own shaft center point and rotates the other screw shaft 51b counterclockwise (direction indicated by arrow R1 in Fig. 9) around their own shaft centers. That is, if the drive from the drive source 57 is transmitted, for example, via the first drive transmission section 58a to each of the screw shafts 51a and 51b, the lifting element 5 rotates the pair of screw shafts 51a and 51b in the same direction around the shaft centers of the pair of screw shafts 51a and 51b.

[0057] If, on the other hand, the drive from the drive source 57 is transmitted via the second drive transmission section 58b to each of the screw shafts 51a and 51b, the lifting element 5 rotates, for example, one screw shaft 51a clockwise (by the arrow R2 in Fig. 9 (indicated direction) around its own shaft center point and rotates the other screw shaft 51b counterclockwise (by the arrow R1 in Fig. 9 direction indicated) around their own shaft center. If, for example, the reverse drive of the drive source 57 is transmitted via the second drive transmission section 58b to each of the screw shafts 51a and 51b, the lifting element 5 rotates one screw shaft 51a counterclockwise (direction indicated by arrow R4 in Fig. 9) around its own shaft center point and rotates the other screw shaft 51b clockwise (direction indicated by arrow R3 in Fig. 9) around their own shaft centers. That is, when the drive from the drive source 57 is transmitted via the second drive transmission section 58b to each of the screw shafts 51a and 51b, the lifting element 5 rotates the pair of screw shafts 51a and 51b in opposite directions around the shaft centers of the pair of screw shafts 51a and 51b.

[0058] When the drive source 57 is driven and the drive from the drive source 57 is transmitted via the first drive transmission section 58a to the pair of screw shafts 51a and 51b, the lifting element 5 operates as follows. In the pair of sliders 53a and 53b, the direction of the first slider screw hole 531 in one slider 53a is opposite to the direction of the second slider screw hole 534 in the other slider 53b. Therefore, in the insertion / removal direction X, one slider 53a comes close to the other slider 53b.

[0059] On the other hand, if the reverse drive of the drive source 57 is transmitted via the first drive transmission section 58a to the pair of screw shafts 51a and 51b, the lifting element 5 operates as follows. In the slider pair 53a and 53b, the direction of the first slider screw hole 531 in one slider 53a is opposite to the direction of the second slider screw hole 534 in the other slider 53b. Therefore, one slider 53a is separated from the other slider 53b in the insertion / removal direction X.

[0060] On the other hand, when the drive source 57 is driven and the drive of the drive source 57 is transmitted via the second drive transmission section 58b to the pair of screw shafts 51a and 51b, the first slider screw hole 531 is screwed to the screw of the other screw shaft 51b, while the second slider screw hole 534 is screwed to the screw of one screw shaft 51a, with respect to the pair of screw shafts 51a and 51b, and the direction of rotation about the shaft center of the other screw shaft 51b is opposite to that about the shaft center of one screw shaft 51a. Therefore, when the drive of the drive source 57 is transmitted via the second drive transmission section 58b to the pair of screw shafts 51a and 51b, the pair of sliders 53a and 53b moves to one side in the insertion / removal direction X, while maintaining a distance between them in the insertion / removal direction X.

[0061] Furthermore, the drive source 57 is driven in the reverse direction, and the reverse drive of the drive source 57 is transmitted via the second drive transmission section 58b to the pair of propeller shafts 51a and 51b. With respect to the pair of propeller shafts 51a and 51b, the first slider screw hole 531 is screwed to the screw of the other propeller shaft 51b, while the second slider screw hole 534 is screwed to the screw of one propeller shaft 51a, and the direction of rotation about the shaft center of the other propeller shaft 51b is opposite to that about the shaft center of one propeller shaft 51a. Therefore, when the reverse drive of the drive source 57 is transmitted via the second drive transmission section 58b to the pair of screw shafts 51a and 51b, the pair of sliders 53a and 53b moves to the other side in the insertion / removal direction X, while a distance between them is maintained in the insertion / removal direction X.

[0062] The pair of sliding guide sections 54a and 54b face each other in the insertion / removal direction X. Each of the sliding guide sections 54a and 54b is designed in the rod shape of a cylinder extending in the insertion / removal direction X.

[0063] Of the pair of sliding guide sections 54a and 54b, the sliding guide section 54a, which is located on the insertion direction X1 side in the insertion / removal direction X, has one end on the insertion direction X1 side that is attached to the first bearing 52a, and one end on the removal direction X2 side that is attached to the second bearing 55a. Furthermore, the sliding guide section 54a is inserted into the second slider through-hole 533 of the slider 53a and guides the movement of the slider 53a in the insertion / removal direction X.

[0064] Of the pair of sliding guide sections 54a and 54b, the other sliding guide section 54b, located on the removal direction X2 side in the insertion / removal direction X, has one end on the insertion direction X1 side, which is attached to the other first bearing 52b, and one end on the removal direction X2 side, which is attached to the other second bearing 55b. Furthermore, the other slide guide section 54b is inserted into the third slide through-hole 535 of the other slide 53b and guides the movement of the other slide 53b in the insertion / removal direction X.

[0065] The connection mechanism 56 has four arms 56a1, 56a2, 56b1, and 56b2. More precisely, the connection mechanism 56 has a pair of first arms 56a1 and 56a2 located on the insertion direction X1 side, and a pair of second arms 56b1 and 56b2 located on the removal direction X2 side. The pair of first arms 56a1 and 56a2 each has a base end on the insertion direction X1 side and a tip end on the removal direction X2 side, with the base end attached to one of the sliders 53a and the tip end to the power supply body 40. The pair of second arms 56b1 and 56b2 each has a base end on the side of the extraction direction X2 and a tip end on the side of the insertion direction X1, with the base end attached to the other glider 53b and the tip end attached to the power supply body 40.

[0066] The lifting element 5 with the above configuration drives the drive source 57 in a state where the power supply fitting 40 is oriented downwards in the vertical direction Z, and brings the slider pair 53a and 53b close together in the insertion / removal direction X when the drive from the drive source 57 is transmitted via the first drive transmission section 58a to the pair of screw shafts 51a and 51b. Then the lifting element 5 lifts, as shown in Fig. 8 and Fig. 9 shows the four arms 56a1, 56a2, 56b1 and 56b2 being brought close to each other, and moves the power supply pass body 40 in the upward direction Z1 by raising the four arms 56a1, 56a2, 56b1 and 56b2.

[0067] On the other hand, the lifting element 5 drives the drive source 57 in the reverse direction in a state where the power supply fitting 40 is arranged in the vertical direction Z in the upward direction Z1, and separates the slider pair 53a and 53b in the insertion / removal direction X when the reverse drive of the drive source 57 is transmitted via the first drive transmission section 58a to the pair of screw shafts 51a and 51b. Then the lifting element 5 lowers, as in Fig. 6 and Fig. 7 shows the four arms 56a1, 56a2, 56b1 and 56b2 being detached by separating the pair of gliders 53a and 53b from each other, and moves the power supply pass body 40 in the downward direction Z2 by laying down the four arms 56a1, 56a2, 56b1 and 56b2.

[0068] Furthermore, the lifting element 5 drives the drive source 57 in a state where the current-receiving locator 3 and the power supply locator 40 are separated from each other in the insertion / removal direction X, and when the drive of the drive source 57 is transmitted via the second drive transmission section 58b to the pair of screw shafts 51a and 51b, the lifting element 5 moves in the insertion / removal direction X in a state in the insertion direction X1 in which the pair of sliders 53a and 53b maintains the distance between them. That is, the lifting element 5 operates as described above, thereby moving the power supply locator 40 in the insertion direction X1 (direction indicated by arrow F in Fig. 9).

[0069] On the other hand, the lifting element 5 drives the drive source 57 in the reverse direction in a state where the current-intake plug 3 and the power supply plug 40 are close together in the insertion / removal direction X, and when the reverse drive of the drive source 57 is transmitted via the second drive transmission section 58b to the pair of screw shafts 51a and 51b, the lifting element 5 moves in the removal direction X2 in the insertion / removal direction X in a state where the pair of sliders 53a and 53b maintains the distance between them. That is, the lifting element 5 operates as described above, moving the power supply plug 40 in the removal direction X2 (direction that is in Fig. 9 is indicated by arrow B).

[0070] The two lifting door sections 59a and 59b are designed on the lifting housing 50 to be opened and closed, and are in an open state when the power supply connector 40 is brought into contact with the two lifting door sections 59a and 59b by the drive of the lifting element 5. When the power supply connector 40 is in the upward direction in the vertical direction Z1, the pair of lifting door sections 59a and 59b is held in an open state by being brought into contact with the four arms 56a1, 56a2, 56b1 and 56b2.On the other hand, the pair of lifting door sections 59a and 59b is forced into a closing direction by providing a pressure element (not shown), and when the power supply pass-through 40 is moved downwards in the vertical direction Z by reversing the lifting element 5, the pair of lifting door sections 59a and 59b is in a closed state by the pressure force of the pressure element, thus suppressing the ingress of foreign substances, such as rainwater, into the lifting housing 50.

[0071] The operation of vehicle charging system 1 with the above configuration is described below. First, as in Fig. As shown in Figure 2, vehicle 2 is not stopped at stopping point 21, the arms 56a1, 56a2, 56b1 and 56b2 of the lifting element 5 are in the down position, and the pair of lifting door sections 59a and 59b is in a closed state. In such a state, as shown in Fig. As shown in Figure 1, vehicle 2 stops at stopping point 21 by means of automatic driving.

[0072] When the vehicle 2, stopped at stopping position 21, is detected by a sensor (not shown), a control unit 10 of the vehicle charging system 1 drives the lifting element 5, thereby raising the four arms 56a1, 56a2, 56b1 and 56b2, thereby opening the pair of lifting door sections 59a and 59b and moving the power supply pass-through body 40 in the upward direction Z1 in the vertical direction Z, as shown in Fig. 10 shown.

[0073] As in Fig. 11 and Fig. As shown in Figure 12, the control unit 10 of the vehicle charging system 1 causes the power supply adapter 40 to retract into the opposite space 35s by driving the lifting element 5, and stops the drive of the lifting element 5 when the power supply ceiling section 441 of the power supply adapter 40 comes into contact with the ceiling wall section 355 of the power pickup adapter 3. In such a state, in the insertion / removal direction X, the position of the power supply adapter 40 in the vertical direction Z coincides with the position of the power pickup adapter 3 in the vertical direction Z. That is, the lifting element 5 is driven so that the power supply adapter 40 is located in the opposite space 35s and the power supply terminals 41 and the power pickup terminals 31 are in an opposite state, in which they are opposite each other in the insertion / removal direction X.The opposite state is described in more detail. The position of the first power supply signal terminal 41a1 in the vertical direction Z coincides with the position of the first current consumption signal terminal 31a1 in the vertical direction Z. Furthermore, the position of the second power supply signal terminal 41a2 in the vertical direction Z coincides with the position of the second current consumption signal terminal 31a2 in the vertical direction Z. Additionally, the position of the first power supply terminal 41b1 in the vertical direction Z coincides with the position of the first current consumption terminal 31b1 in the vertical direction Z. Moreover, the position of the second power supply terminal 41b2 in the vertical direction Z coincides with the position of the second current consumption terminal 31b2 in the vertical direction Z.

[0074] That is, in the present embodiment, the opposite state refers to a state in which the power supply body 40 is located in the opposite space 35s and the position of the power pickup terminals 31 in the vertical direction Z and the position of the power supply terminals 41 in the vertical direction Z coincide. Thus, if the position of the power pickup terminals 31 in the vertical direction Z and the position of the power supply terminals 41 in the vertical direction Z coincide, the opposite state includes a state in which the position of the power pickup terminals 31 in the horizontal direction Y and the position of the power supply terminals 41 in the horizontal direction Y coincide, as shown in Fig. 12, and a state in which the position of the power supply terminals 41 in the lateral direction Y is shifted relative to the position of the power input terminals 31 in the lateral direction Y, as shown in Fig. 15 shown.

[0075] From such a state, the control unit 10 of the vehicle charging system 1 moves the power supply connector 40 in the insertion direction X1 in the insertion / removal direction X by driving the lifting element 5, thereby causing the power supply connector 40 to be inserted into the power pickup connector 3 so that the power pickup terminals 31 and the power supply terminals 41 are in contact with each other, as shown in Fig. 13 and Fig. Figure 14 shows that the control unit 10 of the vehicle charging system 1 brings the first current input signal terminal 31a1 into contact with the first power supply signal terminal 41a1, brings the second current input signal terminal 31a2 into contact with the second power supply signal terminal 41a2, brings the first current input terminal 31b1 into contact with the first power supply terminal 41b1, and brings the second current input terminal 31b2 into contact with the second power supply terminal 41b2.

[0076] Then, the control unit 10 of the vehicle charging system 1 charges the battery 22 via the charging device 49. Following this, the control unit 10 of the vehicle charging system 1 moves the power supply connector 40 in the direction of extraction X2 in the insertion / removal direction X by actuating the lifting element 5, thereby removing the power supply connector 40 from the power receiving connector 3. Afterward, the control unit 10 of the vehicle charging system 1 stops the actuation of the lifting element 5 and stops the movement of the power supply connector 40 in the direction of extraction X2.

[0077] Next, the control unit 10 of the vehicle charging system 1 moves the power supply body 40 downwards in the vertical direction Z2 by driving the lifting element 5, thereby accommodating the power supply body 40 within the lifting housing 50. The pair of lifting door sections 59a and 59b are held closed within the lifting element 5 by the pressure force of the pressure element.

[0078] The vehicle charging system 1 and the power pickup body 3 according to the present embodiment have the following configurations. The power pickup body 3 comprises the power pickup terminals 31, which are electrically connected to the battery 22 provided in the vehicle 2, the power pickup terminal retaining section 34, which holds the power pickup terminals 31, and the opposite space-forming section 35, which is arranged next to the power pickup terminal retaining section 34 in the insertion / removal direction X and forms the opposite space 35s, which is opposite the power pickup terminals 31.When the power supply adapter 40 is located in the opposite space 35s and the power supply terminals 41 and the power pickup terminals 31 are in an opposite state, in which they are opposite each other in the insertion / removal direction X, the lifting element (movement section in insertion / removal direction) 5 causes the power pickup adapter 3 and the power supply adapter 40 to be fitted together by moving the power supply adapter 40 in the direction of the power pickup adapter 3 in the insertion / removal direction X, and electrically connects the battery 22 and the charging device 49 by bringing the power pickup terminals 31 and the power supply terminals 41 into contact with each other.Therefore, according to the present embodiment, the vehicle charging system 1 and the power pickup adapter 3 can electrically connect the power supply terminals 41 and the power pickup terminals 31 when the power supply adapter 40 is moved in the insertion / removal direction X by the lifting element (insertion / removal direction movement section) 5. Consequently, according to the present embodiment, the vehicle charging system 1 and the power pickup adapter 3 can arrange the power pickup terminals 31 along the insertion / removal direction X. Therefore, in the vehicle charging system 1 and the power pickup adapter 3, according to the present embodiment, the power pickup terminals 31 can be arranged horizontally along the insertion / removal direction X, so that the arrangement within the vehicle is not affected.This allows the vehicle charging system 1 and the current-collecting body 3, according to the present embodiment, to suppress the influence on the arrangement of the components forming the vehicle 2 within the vehicle.

[0079] The vehicle charging system 1 and the power pickup adapter 3 according to the present embodiment have the following configurations. The power pickup adapter 3 has a plurality of power pickup terminals 31, and the power pickup terminals 31 are arranged side by side in a direction that differs from the insertion / removal direction X and the vertical direction Z of the vehicle 2. Therefore, the vehicle charging system 1 and the power pickup adapter 3 according to the present embodiment can suppress any interference with the arrangement inside the vehicle even more effectively.

[0080] Furthermore, according to the present embodiment, the vehicle charging system 1 and the opposite space-forming section 35 of the power-collecting connector 3 have guide surfaces 351f, which are arranged on the side of the power-collecting connector 3 in the insertion / removal direction X and, in the opposite state, are opposite the power supply connector 40 in the insertion / removal direction X. The guide surfaces 351f are arranged in a pair, with the power-collecting connection retaining section 34 positioned between them. The distance between the pair of guide surfaces 351f1 and 351f2 in the lateral direction Y decreases towards the power-collecting connector 3 in the insertion / removal direction X.

[0081] Therefore, in the vehicle charging system 1 and the current-collecting body 3 according to the present embodiment, as in Fig. As shown in Figure 15, although the position of each power supply terminal 41, which corresponds to the position of each current pickup terminal 31, is displaced in the insertion / removal direction X when the lifting element 5 is driven to move the power supply adapter 40 in the insertion direction relative to the current pickup adapter 3, the tip end of the power supply adapter 40 on the insertion direction X1 side is in contact with the pair of guide surfaces 351f1 and 351f2, so that the current pickup terminals 31 and the power supply terminals 41 can be in a contactable state from the insertion / removal direction X perspective, in which they can come into contact with each other immediately before installation. As a result, the vehicle charging system 1 and the current pickup adapter 3, according to the present embodiment, can cause the current pickup adapter 3 and the power supply adapter 40 to be reliably mounted together. First modification of the first embodiment

[0082] Fig. Figure 16 is a top view showing a first modification of the first embodiment of the vehicle loading system 1 according to the present invention. In the vehicle loading system 1 according to the first embodiment, the insertion / removal direction X of the vehicle loading system 1 and the longitudinal direction FB of the stopped vehicle 2 coincide, and the lateral direction Y of the vehicle loading system 1 and the vehicle width direction S of the stopped vehicle 2 coincide. On the other hand, in a vehicle loading system 1A according to the first modification, the insertion / removal direction X of the vehicle loading system 1A and the vehicle width direction S of the stopped vehicle 2 coincide, and the lateral direction Y of the vehicle loading system 1A and the longitudinal direction FB of the stopped vehicle 2 coincide.The other configurations of the vehicle charging system 1A according to the first modification are the same as those of the vehicle charging system 1 according to the first embodiment.

[0083] When vehicle 2 stops at stopping position 21, its stopping position shifts in the vehicle width direction S, even though vehicle 2 stops automatically. However, the longitudinal deviation FB of vehicle 2 is smaller than the deviation in the vehicle width direction S at each stop. Therefore, in accordance with the vehicle charging system 1A as modified in the first version, the magnitude of the deviation of the power supply connector 40 relative to the power pickup connector 3 in the insertion / extraction direction X can be minimized. Second modification of the first embodiment

[0084] Fig. Figure 17 is a top view showing a second modification of the first embodiment in a vehicle charging system 1B according to the present invention. More precisely, it is Fig. 17 a side view illustrating a state in which the arms 56a1, 56a2, 56b1 and 56b2 of a lifting element 5B contained in a power supply device 4B are raised in the vehicle charging system 1B according to the second modification of the first embodiment of the present invention.

[0085] The lifting element 5B of the power supply device 4B according to the second modification includes, in addition to the configuration of the lifting element 5 of the power supply device 4 according to the first embodiment, a vertical elastic deformation section 61b and the like. The lifting element 5B comprises a fixed section 61a, which is attached to the tip ends of the four arms 56a1, 56a2, 56b1 and 56b2 in the connection mechanism 56, and the vertical elastic deformation section 61b, which is provided between an upper section of the fixed section 61a and a lower section of the power supply device body 40. The vertical elastic deformation section 61b is designed to be elastically deformable in the vertical direction Z.Therefore, if the lifting element 5B moves the power supply pass-through body 40 in the upward direction Z1 and causes the power supply pass-through body 40 to enter the opposite space 35s, so that the power supply ceiling section 441 (see . Fig. 4) of the power supply pass-through body 40 against the ceiling wall section 355 (see Fig. 3) When the current-receiving fitting body 3 is pressed, the vertical elastic deformation section 61b contracts in the vertical direction Z. In such a state, the lifting element 5B is moved in the insertion direction X1 by the drive of the drive source 57, the current-receiving fitting body 3 and the power supply fitting body 40 are aligned, and the current-receiving terminals 31 and the power supply terminals 41 are brought into contact with each other, so that the battery 22 and the charging device 49 are electrically connected.

[0086] The vehicle charging system 1B and the power pickup adapter 3, according to the present modification, have the following configurations. The lifting element 5B comprises the fixed section 61a, which is attached to the tips of the four arms 56a1, 56a2, 56b1, and 56b2 in the connection mechanism 56, and the vertical elastic deformation section 61b, which is provided between the upper section of the fixed section 61a and the lower section of the power supply adapter 40. Therefore, the position of the power supply adapter 40 in the vertical direction Z can be aligned with the position of the power pickup adapter 3 in the vertical direction Z, so that the power supply adapter 40 can be reliably adapted to the power pickup adapter 3. Third modification of the first embodiment

[0087] Fig. Figure 18 is a top view showing a third modification of the first embodiment in a vehicle charging system 1C according to the present invention.

[0088] A lifting element 5C of a power supply device 4C in the vehicle charging system 1C according to the third modification includes, in addition to the configuration of the lifting element 5B according to the second modification, also wide elastic deformation sections 62a and 62b and the like.

[0089] The fixed section 61a has a pair of bent sections 62c and 62d, which are opposite each other in the lateral direction Y. Furthermore, the lifting element 5C comprises the laterally elastic deformation sections 62a and 62b between the power supply-side sections 443 and 444 in the power supply fitting 40 and the bent section 61c, and the laterally elastic deformation section 62b between the power supply-side section 444 in the power supply fitting 40 and the bent sections 62c and 62d. The laterally elastic deformation sections 62a and 62b are designed to be elastically deformable in the lateral direction Y.Therefore, the power supply insert 40 moves in the width direction Y when the power supply insert 40 comes into contact with the pair of guide surfaces 351f1 and 351f2 when the power supply insert 40 is moved by the lifting element 5C in the insertion direction X1, so that the position of the power supply insert 40 in the width direction Y can be aligned with the position of the power pickup insert 3 in the width direction Y, whereby the power pickup terminals 31 and the power supply terminals 41 are in a contactable state as seen from the insertion / removal direction X. Second embodiment

[0090] Fig. 19 to Fig. Figure 24 shows the drawings illustrating a current-collecting pass-through body 3D according to a second embodiment in a vehicle charging system 1D according to the present invention. Fig. Figure 19 is a perspective view of the current-collecting pass body 3D according to the second embodiment. Fig. Figure 20 is a top view of the current pickup body 3D according to the second embodiment. Fig. 21 to Fig. Figure 24 are schematic views to explain step-by-step the operation of the vehicle charging system 1D according to the present embodiment.

[0091] The current-collecting pass-through body 3 according to the second embodiment comprises, in addition to the configuration of the current-collecting pass-through body 3 according to the first embodiment, a retaining section door 310 which opens and closes the retaining section opening 34o1.

[0092] As in Fig. 19 and Fig. As shown in Figure 20, the holding section door 310 comprises a holding section door body 310a, a substrate 311 and a pressure element 319.

[0093] The retaining section door 310 comprises a pair of door side sections 312a and 312b facing each other in the width direction Y, a pair of opposing walls 313 and 314 facing each other in the insertion / removal direction X, and a door surface section 315 connecting a pair of the two upper ends of the door. The door surface section 315 faces the substrate 311 in the vertical direction Z. The door surface section 315 has an upper door surface end 315u at its end in the upward direction Z1 and a lower door surface end 315d at its end in the downward direction Z2. The lower door surface end 315d is located on the removal direction side X2, and the upper door surface end 315u is located on the insertion direction side X1. In the width direction Y, the lower door surface end 315d and the upper door surface end 315u are inclined with respect to the vertical direction Z and the insertion / removal direction X.

[0094] The substrate 311 is, for example, in the form of a rectangular, flat plate. The pressure element 319 is, for example, a helical spring. For instance, a pair of pressure elements 319 are arranged side by side in the width direction Y. The pair of pressure elements 319a and 319b causes a pointed end of the retaining section door body 310a to bear against an inner surface of the current-collecting ceiling section 341 by the pressure force of the pressure element 319 in a state where no external force is applied, thereby closing the retaining section opening 3401.

[0095] On the other hand, as in Fig. Figure 21 shows a tip end face 401f of a power supply connector 40D on the insertion direction X1 side, with a lower tip end section 401d at its end in the downward direction Z2 and an upper tip end section 401u at its end in the upward direction Z1. The lower tip end section 401d is located on the side of the extraction direction X2, and the upper tip end section 401u is located on the side of the insertion direction X1. In the lateral direction Y, the lower tip end section 401d and the upper tip end section 401u are inclined with respect to the vertical direction Z and the insertion / extraction direction X.

[0096] Next, the operation of the vehicle charging system 1D of the present embodiment will be described with reference to Fig. 21 to Fig. 24 described. As in Fig. As shown in Figure 21, the vehicle charging system 1D moves the power supply body 40D in the upward direction Z1 by driving the lifting element 5. The vehicle charging system 1D then continues to drive the lifting element 5, causing the power supply body 40D to enter the opposite chamber 35s, so that the power supply ceiling section 441 of the power supply body 40D comes into contact with the ceiling wall section 355 of the opposite chamber formation section 35, as shown in Figure 21. Fig. Figure 22 is shown. Afterwards, the vehicle charging system 1D stops the drive of the lifting element 5.

[0097] When the vehicle charging system 1D moves the power supply fitting 40D in the insertion direction X1 by the drive of the lifting element 5, the tip end surface 401f of the power supply fitting 40 comes into contact with the door surface section 315 of the retaining section door body 310a, as shown in Fig. Figure 23 shows that the retaining section door body 310a then moves downwards in the direction Z2 due to the external force based on the movement of the power supply pass-through body 40. At this point, the pressure element 319 extends in the vertical direction Z against the pressure force.

[0098] Subsequently, when the vehicle charging system 1D moves the power supply fitting body 40D further in the direction of insertion X1 by continuously driving the lifting element 5, the retaining section door body 310a moves further downwards, and the door surface section 315 of the retaining section door body 310a comes into contact with the power supply bottom section 442 of the power supply fitting body 40D, causing the retaining section opening 34o1 to be in an open state, as shown in Fig. 24 shown. In such a state, the vehicle charging system 1D causes the power supply body 40D and the power pickup body 3 to be fitted together and brings the power pickup terminals 31 and the power supply terminals 41 into contact with each other, thereby electrically connecting the battery 22 and the charging device 49.

[0099] Then, after the battery 22 is fully charged, when the vehicle charging system 1D moves the power supply body 40D in the removal direction X2 by the drive of the lifting element 5, the tip end surface 401f of the power supply body 40D comes into contact with the door surface section 315 of the retaining section door body 310a. Then, when the lifting element 5 is continuously driven and the power supply body 40D continues to move in the removal direction X2, the contact between the retaining section door body 310a and the power supply body 40D is released, and the retaining section door body 310a moves upwards by the pressure force of the pressure element 319 to close the retaining section opening 34o1.

[0100] That is, the holding section door 310 is in an open state due to the external force based on the movement of the power supply device body 40D through the lifting element 5, exposing the power pickup terminals 31 via the holding section opening 34o1 to the opposite space 35s, and is in a closed state due to the absence of the external force based on the movement of the power supply device body 40D through the lifting element (movement section in insertion / removal direction) 5 to close the holding section opening 34o1.Therefore, in the vehicle charging system 1D and the power pickup body 3D according to the present embodiment, the retaining section door 310 can expose the power pickup terminals 31 to the opposite space 35s to allow contact between the power pickup terminals 31 and the power supply terminals 41 during charging of the battery 22, and the retaining section opening 3401 can close during vehicle 2 travel. As a result, in the vehicle charging system 1D and the power pickup body 3D according to the present embodiment, the retaining section door 310 allows the battery 22 to be charged by the charging device 49, and it prevents foreign material from adhering to the power pickup terminals 31 during vehicle 2 travel. First modification of the second embodiment

[0101] Fig. 25 to Fig. Figure 29 are illustrations to explain a current-collecting pass-through body 3E according to a first modification of the second embodiment in a vehicle charging system 1E according to the present invention. Fig. Figure 25 is a perspective view of the current-collecting pass body 3E according to the first modification of the second embodiment. Fig. 26 to Fig. Figure 29 are schematic views to explain step-by-step the operation of the vehicle charging system 1E according to the present embodiment.

[0102] The current-collecting pass body 3E according to the first modification includes, in addition to the configuration of the current-collecting pass body 3 according to the first embodiment, a retaining section door 320 which opens and closes the retaining section opening 34o1.

[0103] As in Fig. As shown in Figure 25, the retaining section door 320 comprises a substrate 321 which is attached to an outer surface of the current-collecting floor section 342, a retaining section door body 322 which can rotate about a shaft 324 with respect to the substrate 321, and a pressure element 323 provided on the shaft 324.

[0104] The pressure element 323, for example, is a torsion coil spring wound around the shaft 324 and has one end 323a that comes into contact with an inner surface of the current-collecting bottom section 342, and the other end 323b that comes into contact with the retaining section door body 322. In a state where no external force is applied, the pressure element 323 brings the retaining section door 320 into contact with a stopper (not shown) by its own pressure force, thereby closing the retaining section opening 3401.

[0105] Next, the operation of the vehicle charging system 1E according to the present modification will be described with reference to Fig. 26 to Fig. 29 described. As in Fig. As shown in Figure 26, the vehicle charging system 1E moves the power supply body 40 in the upward direction Z1 by driving the lifting element 5, causing the power supply body 40 to enter the opposite space 35s. The vehicle charging system 1E then brings the power supply ceiling section 441 of the power supply body 40 into contact with the ceiling wall section 355 of the opposite space formation section 35 and then stops the drive of the lifting element 5.

[0106] When the vehicle charging system 1E moves the power supply fitting 40 by the drive of the lifting element 5 in the direction of insertion X1, a tip end surface 401g of the power supply fitting 40 on the side of the insertion direction X1 comes into contact with the retaining section door body 322, as shown in Fig. 27. Then the retaining section door body 322 rotates counterclockwise around the shaft 324 in Fig. 27 by the external force, which is based on the movement of the power supply pass body 40 against the pressure force of the pressure element 323, and comes into close proximity to the inner surface of the lower current receiving section 342.

[0107] If, subsequently, the vehicle charging system 1E moves the power supply body 40 further in the insertion direction X1 by continuously driving the lifting element 5, the retaining section door body 322 continues to rotate counterclockwise around the shaft 324 and comes closer to the inner surface of the power pickup floor section 342, as shown in Fig. 28 shown.

[0108] When the vehicle charging system 1E subsequently moves the power supply body 40 further in the direction of insertion X1 by continuously driving the lifting element 5, the retaining section door body 322 comes into contact with the power supply lower part 442 of the power supply body 40, causing the retaining section opening 3401 to be in an open state. In such a state, the vehicle charging system 1E causes the power supply body 40 to be attached to the power pickup body 3 and brings the power pickup terminals 31 and the power supply terminals 41 into contact with each other, thereby electrically connecting the battery 22 and the charging device 49.

[0109] Then, after the battery 22 is fully charged, when the vehicle charging system 1E moves the power supply body 40 in the removal direction X2 by the drive of the lifting element 5, the contact between the power supply body 40 and the retaining section door body 322 is released, and the retaining section door body 322 rotates clockwise by the pressure force of the pressure element 323 to close the retaining section opening 34o1, as shown in Fig. 29 shown.

[0110] The vehicle charging system 1E according to the present modification has the same function and effect as the vehicle charging system 1D according to the second embodiment. Second modification of the second embodiment

[0111] Fig. 30 to Fig. Figure 34 are drawings illustrating a current-collecting pass-through body 3F according to a second modification of the second embodiment in a vehicle charging system 1F according to the present invention. Fig. Figure 30 is a perspective view of the current-collecting pass body 3F according to the second modification of the second embodiment. Fig. 31, Fig. 32 and Fig. Figure 34 are schematic views to sequentially explain the operation of the vehicle charging system 1F according to the present embodiment. Fig. Figure 33 is a perspective view illustrating the operation of the vehicle charging system 1F according to the present embodiment.

[0112] As in Fig. 31 and Fig. As shown in Figure 34, a section 35F forming the opposite space is designed in a tubular shape according to the present modification, the length of which in the vertical direction Z is longer than that of the power-intake connection holding section 34 in the vertical direction Z. In addition, the opposite space-forming section 35F is provided with a door body 332 which is configured to be movable in the vertical direction Z within the opposite space-forming section 35F.

[0113] The door body 332 comprises a retaining section door 332a, which opens and closes the retaining section opening 34o1, and a molded section door 332b, which opens and closes a molded section opening 35o2. Furthermore, the current-collecting interface 3F comprises pressure elements 333 between the floor 25 of the vehicle 2 and the molded section door 332b of the door body 332 in the vertical direction Z. In the current-collecting interface 3F of the present embodiment, four pressure elements 333 are provided between the floor 25 of the vehicle 2 and the molded section door 332b. The pressure element 333 is z. B. a coil spring and extends in the vertical direction Z. When no external force is applied, the retaining section door 332a closes the retaining section opening 34o1 by means of the pressure elements 333 and the molding section door 332b closes the molding section opening 35o2 by means of the pressure elements 333, as in Fig. 31 shown.

[0114] Next, the operation of the vehicle charging system 1F according to the present modification will be described with reference to Fig. 31 to Fig. 34 described. As in Fig. As shown in Figure 31, the vehicle charging system 1F moves the power supply adapter body 40 in the upward direction Z1 by driving the lifting element 5. The vehicle charging system 1F then continues to drive the lifting element 5, causing the power supply ceiling section 441 of the power supply adapter body 40 to come into contact with the forming section door 332b, moving the door body 332 in the upward direction Z1 against the compressive force of the pressure elements 333 to cause the power supply adapter body 40 to enter the opposite space 35s, and then stopping the drive of the lifting element 5, as shown in Figure 31. Fig. 32 shown.

[0115] At this time, the upward movement of the door body 332 in the direction Z1 opens the holding section door 332a the holding section opening 34o1 and the molding section door 332b the molding section opening 35o2.

[0116] The vehicle charging system 1F then moves the power supply body 40 by means of the drive of the lifting element 5 in the direction of insertion X1, causing the power supply body 40 to be installed in the power pickup body 3F and bringing the power pickup terminals 31 and the power supply terminals 41 into contact with each other, thereby electrically connecting the battery 22 and the charging device 49.

[0117] Then, after battery 22 is fully charged, the vehicle charging system 1F moves the power supply body 40 in the extraction direction X2 by means of the drive of the lifting element 5. Afterwards, the vehicle charging system 1F stops the drive of the lifting element 5, drives the lifting element 5 again to move the power supply body 40 in the downward direction Z2, and moves the power supply body 40 back out of the opposite space 35s. Then the contact between the molded section door 332b of the door body 332 and the power supply ceiling section 441 of the power supply fitting body 40 is released, so that, by the pressure force of the pressure elements 333, the retaining section door 332a of the door body 332 is in a closed state to close the retaining section opening 34o1, and the molded section door 332b of the door body 332 is in a closed state to close the molded section opening 35o2, as shown in Fig. 31 shown.

[0118] The vehicle charging system 1F and the power pickup body 3F, according to the present modification, have the following configurations. The molded door 332b is in an open state due to the external force based on the movement of the power supply body 40 through the movement section in the vertical direction, connecting the opposite space 35s to an outside via the molded opening 35o2, and is in a closed state due to the absence of the external force based on the movement of the power supply body 40 through the vertical movement section to close the molded opening 35o2.Therefore, according to the present embodiment, the vehicle charging system 1 and the power pickup body 3 can connect the opposite chamber 35s to an outer surface, causing the power supply body 40 to enter the opposite chamber 35s during battery 22 charging and to close the molded section opening 35o2 with the molded section door 332b while the vehicle 2 is in motion. As a result, the vehicle charging system 1 and the power pickup body 3 allow the battery 22 to be charged by the charging device 49 and the retaining section opening 34o1 to be closed with the retaining section door 332a and the molded section opening 35o2 to be closed with the molded section door 332b while the vehicle 2 is in motion, thus preventing foreign material from adhering to the power pickup terminals 31. Third embodiment

[0119] Fig. Figure 35 is a perspective view to illustrate a power supply body 40G according to a third embodiment in a vehicle charging system 1G according to the present invention. Fig. Figure 36 is a perspective view to illustrate a current-collecting pass body 3G according to the third embodiment in the vehicle charging system 1G according to the present invention.

[0120] As in Fig. As shown in Figure 35, the power supply body 40G in the vehicle charging system 1G according to the third embodiment has a power supply ceiling section 441i, which is opposite the power supply bottom section 442 in the vertical direction Z. The power supply ceiling section 441i has a first ceiling forming section 441i1 and a second ceiling forming section 441i2, and a convex section 448, projecting in the upward direction Z1, is formed by the first ceiling forming section 441i1 and the second ceiling forming section 441i2 on a contact surface 448a located on a surface side of the power supply ceiling section 441i. The convex section 448 extends in the insertion / removal direction X.

[0121] As in Fig. As shown in Figure 36, the current-collecting connection retaining section 34G in a current-collecting body 3G according to the third embodiment in the vehicle charging system 1G has a current-collecting ceiling section 341i in the upward direction Z1. The current-collecting ceiling section 341i is formed by a first ceiling-forming section 341i1 and a second ceiling-forming section 341i2. Furthermore, a concave section, which is recessed in the direction of the upward direction Z1, is formed by the first ceiling-forming section 341i1 and the second ceiling-forming section 341i2 on a ceiling surface located on a lower surface side of the current-collecting ceiling section 341i. The concave section can engage in the convex section 448 of the power supply body 40G.

[0122] The opposite space formation section 35 in the power supply pass-through body 3G has a ceiling wall section 355i in the upward direction Z1. The ceiling wall section 355i is formed by a first ceiling formation section 355i1 and a second ceiling formation section 355i2. Furthermore, a concave section 358, which is recessed in the direction of the upward direction Z1, is formed on a ceiling surface 358a located on a lower surface side of the ceiling wall section 355i. The concave section 358 can engage with the convex section 448 of the power supply pass-through body 40G.

[0123] Furthermore, in the current-collecting body 3G, the concave section of the current-collecting connection holding section 34G and the concave section 358 of the opposite space-forming section 35 each extend in the insertion / removal direction X, and one end of the concave section on the removal direction X2 side and one end of the concave section 358 on the insertion direction X1 side are formed continuously in the insertion / removal direction X.

[0124] In the vehicle charging system 1G according to the present embodiment, when the power supply fitting 40G moves in the upward direction Z1 by the drive of the lifting element 5 and the contact surface 448a of the power supply ceiling section 441i of the power supply fitting 40G is brought into contact with the ceiling surface 358a of the ceiling wall section 355i of the power pickup fitting 3G, the convex section 448 of the power supply fitting 40G engages in the concave section 358 of the power pickup fitting 3G, and the axial direction of the power supply terminals 41 becomes parallel to the axial direction of the power pickup terminals 31 along the insertion / removal direction X.Thus, in such a state, when the power supply fitting 40G is moved in the insertion direction X1, the convex section 448 in the power supply fitting 40G engages in the concave section formed in a power pickup terminal retaining section 34G, and the power supply terminals 41 come into contact with the power pickup terminals 31.

[0125] It should be noted that in the previously described embodiment, the convex section 448 is formed in the power supply body 40G and the concave section 358 is formed in the current pickup body 3G. However, the present embodiment is not limited to this, and a concave section can be formed in the power supply body 40G and a convex section can be formed in the current pickup body 3G.

[0126] The vehicle charging system 1G and the power pickup body 3G according to the present embodiment have the following configurations. Between the cover surface 358a and the contact surface 448a, a surface with the convex section 448 extending in the insertion / removal direction X is formed, and the other surface is formed with the concave section 358 engaging the convex section 448 and extending in the insertion / removal direction X. When the convex section 448 and the concave section 358 engage in opposite directions, the axial direction of the power supply terminals 41 becomes parallel to the axial direction of the power pickup terminals 31.Therefore, in the vehicle charging system 1G and the power pickup body 3G according to the present embodiment, the axial direction of the power supply connections 41 is parallel to the axial direction of the power pickup connections 31 by the convex section 448 and the concave section 358. Consequently, the vehicle charging system 1G and the power pickup body 3G according to the present embodiment can reliably perform an assembly between the power pickup body 3G and the power supply body 40G. First modification of the third embodiment

[0127] Fig. Figure 37 is a perspective view to illustrate a power supply body 40H and a power pickup body 3H according to a first modification of the third embodiment in a vehicle charging system 1H according to the present invention. Fig. Figure 38 is a cross-sectional view showing a contact surface 449a of the power supply connector 40H and a ceiling surface 359a of the current pickup connector 3H. It should be noted that in Fig. 37 the power supply body 40H indicated by the solid line shows the positions of the convex sections 449 which are provided on the contact surface 449a for the sake of simplicity, and similarly to other embodiments and modifications, in the vehicle charging system 1H according to the present embodiment the power supply body 40H is not arranged at a position outside the opposite space 35s in the current receiving body 3H.

[0128] The contact surface 449a of the power supply body 40H in the vehicle charging system 1H according to the present modification has a plurality of convex sections 449 that project upwards, as shown in Fig. 37 and Fig. Figure 38 shows the convex sections 449 extending in the insertion / removal direction X. Furthermore, each convex section 449 is parallel to the insertion / removal direction X. Additionally, the convex sections 449 are arranged at equal intervals in the width direction Y.

[0129] The ceiling surface 359a, which is a lower surface of a ceiling wall section 355H of the power-collecting pass-through body 3H, is formed with a plurality of concave sections 359. The concave section 359 can engage with any of the convex sections 449 and is recessed in the upward direction Z1 from a lower surface of the ceiling surface 359a. The concave sections 359 each extend in the insertion / removal direction X. Furthermore, each concave section 359 runs parallel to the insertion / removal direction X. The concave section 359 has a plurality of first concave sections 359m and a plurality of second concave sections 359s.

[0130] The first concave sections 359m are arranged on the side of the power pickup connection holding section 34 in the insertion / withdrawal direction X, in the insertion / withdrawal direction X.

[0131] The second concave sections 359s are located at positions outside the insertion direction X1 on the side of the current-input connection holding section 34 in the insertion / removal direction X and are each located on both sides of the first concave sections 359m. Furthermore, the second concave sections 359s are spaced equally apart in the lateral direction Y. In addition, the lateral spacing between the second concave sections 359s is the same as the lateral spacing between the first concave sections 359m.

[0132] When, in the vehicle charging system 1H according to the present embodiment, the power supply fitting 40H moves in the upward direction Z1 by the drive of the lifting element 5 and the contact surface 449a of the power supply ceiling section 441 of the power supply fitting 40H is brought into contact with the ceiling surface 359a of the ceiling wall section 355 of the power pickup fitting 3H, the convex sections 449 of the power supply fitting 40H engage in the concave sections 359 of the power pickup fitting 3H, and the axial direction of the power supply connections 41 becomes parallel to the axial direction of the power pickup connections 31 along the insertion / removal direction X.In such a state, the power supply body 40H is located in the opposite space 35s, and the positions of the power supply terminals 41 in the vertical direction Z and the positions of the current pickup terminals 31 in the vertical direction Z coincide (opposite state).

[0133] In the opposite state, when part of the convex sections 449 and the first concave sections 359m are engaged together and part of the convex sections 449 and the second concave sections 359s are engaged together, the position of each power supply terminal 41 in the lateral direction Y is displaced from the position of each corresponding power intake terminal 31 in the lateral direction Y.When, in the vehicle charging system 1H according to the present embodiment, the power supply adapter 40H is moved in the insertion direction X1 by the drive of the lifting element 5, the power supply adapter 40H comes into contact with the pair of guide surfaces 351f1 and 351f2 and moves in the lateral direction Y, so that the current pickup terminals 31 and the power supply terminals 41 can be in a contactable state in which they can come into contact with each other immediately before installation when viewed from the insertion / removal direction X. The contactable state means a state in which the positions of the current pickup terminals 31 and the positions of the power supply terminals 41 in the lateral direction Y coincide.In such a contactable state, the power supply terminals 41 can be brought into contact with the power pickup terminals 31 when the power supply terminals 41 are simply moved in the insertion direction X1 by the drive of the lifting element 5.

[0134] In the above modification, the convex sections 449 are formed on the power supply terminal body 40H and the concave sections 359 on the current pickup terminal body 3H. However, the modification of the present embodiment is not limited to this, and concave sections can also be formed on the power supply terminal body 40H and convex sections can also be formed on the current pickup terminal body 3H.

[0135] The vehicle charging system 1H and the power pickup body 3H, according to the present modification, have the following configurations. Between the top surface 359a and the contact surface 449a, one surface is provided with convex sections 449 extending in the insertion / removal direction X, and the other surface is formed with concave sections 359 engaging with the convex sections 449 and extending in the insertion / removal direction X. When the convex sections 449 and the concave sections 359 are engaged in an opposite state, the axial direction of the power supply terminals 41 is parallel to the axial direction of the power pickup terminals 31.Therefore, in the vehicle charging system 1H and the power pickup body 3H according to the present modification, the axial direction of the power supply terminals 41 can be made parallel to the axial direction of the power pickup terminals 31 by the convex section 449 and the concave section 359. Consequently, in the vehicle charging system 1H and the power pickup body 3H according to the present modification, when the power supply body 40H moves close to the power pickup body 3H in the insertion / removal direction X by the lifting element 5 (movement section in the insertion / removal direction), the power supply body 40H is brought into contact with the pair of guide surfaces 351f1 and 351f2, so that the axial direction of the power supply terminals 41 becomes parallel to the axial direction of the power pickup terminals 31 when the power supply body 40H moves in the lateral direction Y.Furthermore, in the aforementioned installable state, it is possible to maintain the condition in which the axial direction of the power supply terminals 41 is parallel to the axial direction of the current pickup terminals 31 when the power supply adapter 40 moves in the insertion / removal direction X near the current pickup adapter 3 through the lifting element 5 (movement section in the insertion / removal direction). Consequently, the vehicle charging system 1H and the current pickup adapter 3H can reliably perform an assembly between the current pickup adapter 3H and the power supply adapter 40H according to the present embodiment. Fourth embodiment

[0136] Fig. 39 to Fig. Figure 44 shows a power supply device 4I according to a fourth embodiment in the vehicle charging system 1I according to the present invention. The first embodiment, in which the power supply device 4 is, for example, recessed in the parking space 21 of the vehicle 2, was described previously. However, the power supply device 4I according to the present embodiment differs from the power supply device 4 of the first embodiment in that the power supply device 4I is provided on the floor of the parking space 21 of the vehicle 2.

[0137] Fig. Figure 39 is a top view showing a lifting element 5I of the power supply device 4I of the fourth embodiment of the present invention. Fig. Figure 40 is a side view showing the lifting element 5I. Fig. Figure 41 is a perspective view showing a lifting mechanism 74 contained in the lifting element 5I. Fig. Figure 42 is a perspective view showing successively the operation of the lifting element 5I of the present embodiment. Fig. Figure 43 is a perspective view showing the sequential operation of the lifting element 5I of the present embodiment. Fig. Figure 44 is a perspective view illustrating successively the operation of the lifting element 5I of the present embodiment.

[0138] The lifting element 5I in the power supply device 4I of the present embodiment comprises a lifting housing 71, an extension and retraction section 72, a pivoting mechanism 73, and the lifting mechanism 74. The lifting housing 71 has a housing body 71a and a cover 71b. The cover 71b is attached at one end to the top of the housing body 71a by a hinge so that it can be opened and closed. In a state in which the cover 71b is closed with respect to the housing body 71a, the extension and retraction section 72, the pivoting mechanism 73, and the lifting mechanism 74 are housed within the housing body 71a and the cover 71b. On the other hand, in a state where the cover 71b is open in relation to the housing body 71a, the insertion and retraction section 72, the pivoting mechanism 73 and the lifting mechanism 74 are advanced from the inside of the housing body 71a, as described below.

[0139] The insertion and removal section 72 comprises an essentially parallelepiped-shaped insertion and removal body 72a extending in the insertion / removal direction X, a linear motion mechanism 72b provided within the housing body 71a to move the insertion and removal body 72a linearly in the forward / reverse direction (longitudinal direction), and a first motor driving the linear motion mechanism 72b.

[0140] The linear motion mechanism 72b of the present embodiment has a rack 72b1 and a pinion 72b2. The rack 72b1 is attached to the bottom surface inside the housing body 71a, and the first motor for rotating the pinion 72b2 is attached to a base end of the extension and retraction body 72a. By rotating the first motor forwards and backwards, the extension and retraction body 72a can be caused to move forwards and backwards relative to the housing body 71a, as indicated by arrow b1.

[0141] The swivel mechanism 73 comprises a swivel base end 73a, a connecting section 73b, a swivel caster mounting section 73c and a swivel caster 73d.

[0142] The pivot base end 73a is attached to a pointed end of the extension and retraction body 72a via the connecting section 73b. More precisely, the pivot base end 73a is connected to the extension and retraction body 72a via the connecting section 73b in such a way that it can pivot about a pivot shaft j1.

[0143] The connecting section 73b has a rotary gear designed to rotate about the pivot shaft j1 and an output gear mounted on an output shaft of a second motor. The rotary gear and the output gear engage with each other to drive the second motor, thereby pivoting the pivot base end 73a about the pivot shaft j1 relative to the tip end of the extension / retraction body 72a. The pivoting mechanism 73 of the present embodiment pivots the pivot base end 73a about the pivot shaft j1 in a direction relative to the tip end of the extension / retraction body 72a by driving the second motor (indicated by arrow b2 in the figure). Fig. 39) and pivots the pivot base end 73a about the pivot shaft j1 in the other direction with respect to the tip end of the protruding and retracting body 72a by the reverse drive of the second motor (indicated by the arrow b2 in Fig. 39).

[0144] The caster mounting section 73c is a section for mounting the caster 73d. Furthermore, the caster mounting section 73c has a concave section 73c1 for receiving a lifting mechanism section 74L of the lifting mechanism 74 when the power supply body 40 is in the lowest position, as defined by a two-point chain line in Fig. 40 displayed (see Fig. 41).

[0145] The swivel caster 73d is attached to the underside of the swivel caster mounting section 73c. ​​Furthermore, the swivel caster 73d can freely change its direction, rotating by changing its direction according to the linear movement of the extension and retraction body 72a and the pivoting movement of the pivot base end 73a, and supporting the extension and retraction body 72a and the pivot base end 73a, while preventing the extension and retraction body 72a and the pivot base end 73a, which protrude from the lifting housing 71, from coming into contact with the ground.

[0146] The lifting mechanism 74 moves the power supply insert 40 in the vertical direction Z. More precisely, the lifting mechanism 74 is configured to move a power supply insert mounting section 749 (up and down) in the vertical direction Z, as indicated by arrow b3, while maintaining the position of the power supply insert mounting section 749. The lifting mechanism 74 has a base section 741 attached to a tip end of the pivot base end 73a and is provided at its tip end with the power supply insert mounting section 749, which has a plate shape and to which the power supply insert 40 is mounted.

[0147] Fig. Figure 41 is a perspective view showing the lifting mechanism 74. Fig. 41 is the power supply body 40, which is mounted on the power supply body mounting section 749, represented by a virtual line.

[0148] The lifting mechanism 74 comprises the lifting mechanism section 74L and a third motor M3 that drives the lifting mechanism section 74L.

[0149] The lifting mechanism section 74L has a base end that is attached to the caster mounting section 73c and a tip end to which the power supply adapter 40 is attached, and is foldable. When the lifting mechanism section 74L is folded and the power supply adapter 40 is in its lowest position, the folded lifting mechanism section 74L is housed in the concave section 73c1 of the caster mounting section 73c.

[0150] The lifting mechanism section 74L of the present embodiment has four parallel joint mechanisms L1 to L4. The parallel joint mechanisms L1 and L2 and the parallel joint mechanisms L3 and L4 are bilaterally symmetrical to each other, and the respective parts are described by using the same reference numerals.

[0151] The base section 741 of the lifting mechanism section 74L is attached to the bottom of the concave section 73c1 of the caster mounting section 73c. ​​One end of the connecting elements 742 and 743 of the parallel linkage mechanism L1 and one end of the connecting elements 742 and 743 of the parallel linkage mechanism L3 are rotatably attached to a pair of mechanism mounting sections 741a and 741b on the right and left sides of the base section 741, respectively.

[0152] In the lifting mechanism section 74L of the present embodiment, one end of the connecting element 742 of the parallel connection mechanism L1 and one end of the connecting element 742 of the parallel connection mechanism L3 are connected to each other by a pivot shaft 742x, and the pivot shaft 742x is rotatably mounted by the pair of mechanism mounting sections 741a and 741b. Furthermore, in the lifting mechanism section 74L, one end of the connecting element 742 of the parallel connection mechanism L1 and one end of the connecting element 742 of the parallel connection mechanism L3 are connected to each other by a pivot shaft 743x, and the pivot shaft 743x is rotatably mounted by the pair of mechanism mounting sections 741a and 741b.

[0153] The other ends of the connecting elements 742 and 743 of the parallel connection mechanism L1 are rotatably attached to a substantially triangular connecting section 744. Furthermore, one end of the connecting elements 745 and 746 of the parallel connection mechanism L2 are rotatably attached to the connecting section 744. The parallel connection mechanism L1 of the present embodiment is attached to the connecting section 744 such that the other end of the connecting element 743 and one end of the connecting element 746 overlap. In addition, the connecting element 742 and the connecting element 745 are provided with locking sections 742a and 745a, respectively, to lock them together upon contact. The configurations of the parallel connection mechanisms L1 and L2 are the same for the parallel connection mechanisms L3 and L4.

[0154] The other ends of the connecting elements 745 and 746 of each of the parallel connecting mechanisms L2 and L4 are rotatably attached to connecting mounting sections 748a on both the right and left sides of a movable part 748, which is connected to the power supply body mounting section 749. The movable part 748 is formed integrally with the power supply body mounting section 749. That is to say, the movable part 748 and the power supply body mounting section 749 are elements for mounting the power supply body 40.

[0155] Furthermore, the third motor M3 is attached to the underside of the concave section 73c1 for operating the lifting mechanism section 74L. A pulley 751 is attached to a motor shaft of the third motor M3. A belt 752 is tensioned over the pulley 751 and a pulley 753 attached to the rotating shaft 742x, so that the rotation of the third motor M3 is transmitted to the rotating shaft 742x.

[0156] By rotating the third motor M3 forwards and backwards, the rotating shaft 742x rotates forwards and backwards, thereby rotating the connecting element 742, as indicated by arrows b4 and b5. While the connecting element 742 rotates, the connecting element 743 also rotates.

[0157] When the connecting element 742 rotates in the direction of arrow b4, the connecting element 745 rotates through the locking sections 742a and 745a in the direction of arrow b6, so that the connecting element 746 also rotates in the same direction and the moving part 748 and the power supply dowel pin mounting section 749 move in the upward direction Z1. Conversely, when the connecting element 742 rotates in the direction of arrow b5, the connecting element 745 rotates in the direction of arrow b7 through the locking sections 742a and 745a, so that the connecting element 746 also rotates in the same direction and the moving part 748 and the power supply dowel pin mounting section 749 move in the downward direction Z2.As previously described, the connecting element 745, which rotates in conjunction with the rotation of the connecting element 742, rotates in a direction opposite to that of the connecting element 742 (rotates in reverse).

[0158] Furthermore, in a state in which the vehicle 2 is not stopped in the holding position 21, the lifting element 5I of the power supply device 4I accommodates the extension and retraction section 72, the pivoting mechanism 73 and the lifting mechanism 74 within the lifting housing 71, as shown in Fig. 42 shown.

[0159] When vehicle 2 is stopped in stopping position 21, the lifting element 5I pushes the extension and retraction section 72 out of the lifting housing 71, thereby exposing the extension and retraction section 72, the pivoting mechanism 73 and the lifting mechanism 74 from the lifting housing 71 to the outside, as shown in Fig. 43 shown.

[0160] Next, as in Fig. As shown in Figure 44, the lifting element 5I moves the power supply insert 40 upwards by driving the lifting mechanism 74. The lifting element 5I also drives the pivoting mechanism 73 when required. From this position, the lifting element 5I further moves the extension and retraction section 72 relative to the lifting housing 71, thereby moving the power supply insert 40 in the insertion direction X1 and causing it to be aligned with a current-collecting insert 3.

[0161] It should be noted that the configuration of each of the above embodiments and the configuration of each modification can be formed by combining one part of the configurations with another part of the configurations.

[0162] It should be noted that the vehicle charging systems 1, 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, and 1I, as described above, involve current being supplied from the charging device 49 located outside the vehicle to the battery 22 mounted on the vehicle 2, thus charging the battery 22. However, the vehicle charging systems 1, 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, and 1I, as described in the present embodiments, are not limited to this; current can also be supplied from the battery 22 mounted on the vehicle 2 to a storage battery of the charging device 49 located outside the vehicle (e.g., in a residential building), thus charging the storage battery.

However, the vehicle charging systems 1, 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, and 1I according to the present embodiments are not limited to these; Even if each of the power pickup body 3, 3D, 3E, 3F, 3G and 3H has the power pickup connection holding section 34 and not the opposite space formation section 35, a concave section in the floor 25 of the vehicle 2 can be used as an opposite space formation section.

[0165] Furthermore, the vehicle charging systems 1, 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, and 1I according to the above embodiments have been described, in which two current-collecting ports 31 are arranged side by side in the width direction Y in the current-collecting bodies 3, 3D, 3E, 3F, 3G, and 3H. However, the current-collecting bodies 3, 3D, 3E, 3F, 3G, and 3H in the vehicle charging systems 1, 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, and 1I according to the present embodiments are not limited to this; a plurality of three or more current-collecting ports 31 can also be arranged side by side in the width direction Y.
